Command Reference, Cisco IOS XE Everest 16.5.1a (Catalyst 9500 Switches) 1

boot ipxeTo configure the iPXE boot, use the boot ipxe command in global configuration mode. To disable theconfiguration, use the no form of this command.

boot ipxe{forever | timeout | seconds}switch switch-number

no boot ipxe{forever | timeout | seconds}switch switch-number

Syntax Description Attempts iPXE boot forever.forever

Configures a timeout in seconds for iPXE network boot. Valid valuesare from 1 to 2147483647.

timeout seconds

Enables iPXE boot for switches in the stack. Valid values are from 0 to9.

switch switch-number

Command Default

Command Modes Global configuration (config)

Command History ModificationRelease

This command was introduced.Cisco IOS XE Denali 16.3.2

Usage Guidelines iPXE is an open source implementation of Preboot eXecution Environment (PXE). The bootloaders boot animage located on an HTTP, FTP, or a TFTP server.

If the forever keyword is configured, the switch sends Dynamic Host Control Protcol (DHCP) requestsforever. If the timeout keyword is configured, DHCP requests are sent for the specified amount of time, andwhen the timeout expires, the switch reverts to device boot.

Examples The following example shows how to configure an iPXE boot timeout for switch 2:Device(config)# boot ipxe timeout 240 switch 2

Command Reference, Cisco IOS XE Everest 16.5.1a (Catalyst 9500 Switches)2

boot manualTo configure manual boot, use the boot manual command in global configuration mode. To remove theconfiguration, use the no form of this command.

boot manual switch switch-number

no boot manual switch switch-number

Syntax Description Configures manual boot for the switches in the stack.switch swtich-number

Command Default Manual boot is enabled.




Usage Guidelines When manual boot is disabled, and the switch reloads, the boot process starts automatically. When manualboot is disabled, the bootloader determines whether to execute a device boot or a network boot based on theconfigured value of the iPXE ROMMON variable.

Examples The following example shows how to configure manual boot for switch 2:Device(config)# boot manual switch 2

Usage Guidelines

Examples


Programmabilitydefault boot

installTo install Software Maintenance Upgrade (SMU) packages, use the install command in privileged EXECmode.

install {activate | file {bootflash: | flash: | webui:} [prompt-level {all | none}] | add file {bootflash: | flash:| ftp: | http: | https: | rcp: | scp: | tftp: | webui:} [activate [prompt-level {all | none}]] | commit | deactivatefile {bootflash: | flash: | webui:} [prompt-level {all | none}] | remove {file {bootflash: | flash: | ftp: | http:| https: | rcp: | scp: | tftp: | webui:}| inactive } | rollback to {base | committed | id {install-ID }}}

Syntax Description Validates whether the SMU is added through theinstall add command, and restarts the Netconfprocesses (confd and opdatamgrd).

This keyword runs a compatibility check, updatespackage status, and if the package can be restarted,it triggers post-install scripts to restart the necessaryprocesses, or triggers a reload for non-restartablepackages.

activate

Specifies the package to be activated.file

Specifies the location of the installed package.{bootflash: | flash: | http: | https: | rcp: | scp: |tftp:webui:}

(Optional) Prompts the user about installationactivities.

For example, the activate keyword, automaticallytriggers a reload for packages that require a reload.Before activating the packag, a message will promptusers as to whether they want to continue.

The all keyword allows you to enable prompts. Thenone keyword diables prompts.

prompt-level {all | none}

Copies files from a remote location (via FTP, TFTP)to a device and performs Software MaintenanceUpgrade (SMU) compatibility check for the platformand image versions.

This keyword runs base compatibility checks toensure that a specified package is supported on aplatform. It also adds an entry in the package file,so that the status can be monitored and maintained.

add

Specifies the package to be added.{http: | https: | rcp: | scp: | tftp:}


Programmabilityinstall

Makes SMU changes persistent over reloads.

You can do a commit after activating a package,while the system is up, or after the first reload. If apackage is activated, but not committed, it remainsactive after the first reload, but not after the secondreload.

commit

Deactivates an installed package.

Deactivating a package also updates the packagestatus and triggers a process restart or a reload.

deactivate

Remove installed packages.

The package file is removed from the file system.The remove keyword can only be used on packagesthat are currently inactive.

remove

Removes all inactive packages from the device.inactive

Rollbacks the data model interface (DMI) package(DMP) SMU to the base version, the last committedversion, or a known commit ID, and restarts Netconfprocesses.

rollback

Returns to the base image.to base

Returns to the installation state when the last commitoperation was performed.

committed

Returns to the specific install point ID.

Valid values are from 1 to 4294967295.

id install-ID

Command Default Packages are not installed.

This command was introduced.Cisco IOS XE Everest 16.5.1

Usage Guidelines An SMU is a package that can be installed on a system to provide a patch fix or security resolution to a releasedimage. This package contain a minimal set of files for patching the release along with some metadata thatdescribes the contents of the package.



Packages msut be added prior to activating the SMU.

A package must be deactivated, before it is removed from the bootflash. A removed packaged must be addedagain.

Syntax Description (Optional) IP address of the host.host_ip_address

Usage Guidelines The ping and ping4 commands are the same.

The ping command is a very common method for troubleshooting the accessibility of devices

A timeout is implemented at the bootloader device prompt, that allows the bootloader to poll the TCP stackevery 200 ms. As a result, the bootloader may take up to 200 ms to respond to pings. However, when thebootloader is downloading a file, and thus actively polling for new packets, it responds to ping quickly.

Examples The following is sample output from the ping command:Device: ping 10.29.27.5

Ping 10.29.27.5 with 32 bytes of data ...Host 10.29.27.5 is alive.

The following is sample output from the ping host_ip_address retries command:Device: ping 10 6.29.27.5 6
